well the AMD rollers read a lot lower than Powerstation! Although I can see from the figures they didn't put in the correct atmospheric details though which will effect it, 0c apparently today! So the correction factor is out. Although not so important for this as the variables were the same between the runs, so its a fair comparison for the before and after.
Before 461 bhp / 534 lb/ft torque ( more like 490 lb/ft but is spiked early on because of the auto box.
After 486bhp / 526 lb/ft. Broadly about 20 lb/ft increase across the board and holds the power a little better between 6000 and 6500 rpm (redline). before remap power at 6000rpm was 460bhp, after was 482bhp, so +22bhp, at 6500rpm its 420bhp before and 470 after, so + 50bhp.
Haven't really had a chance to feel any difference yet, but Vmax should be a bit more interesting.
